The old “early bird gets the worm” colloquialism certainly was coined by a fisherman in the summer. No doubt in my mind. Because there is no time that is more true than in the summer—at least for crappie fishing. It’s not because it’s cooler although that certainly makes it more enjoyable. It’s because crappie are just more active in low light situations.
“They just seem to shut down after about 10am,” Tony Sheppard said. Sheppard is who got me going early in the summer to chase crappie and I’m grateful he did.
Absolutely, they will still bite in the middle of the day, but it seems like you can set your watch by their activity level tapering off around 9 or 10 am this time of year. I try to be on the water by at least 5:45 or 6 am. I want to do most of my damage in 3 hours in the morning.
You can do the same thing in the evening, but it seems to me the window is shorter. When the sun gets down behind the trees around 7pm, you might get until 8pm to fish for them in low light. So I definitely prefer the morning as darkness has cooled the water several degrees and they low light is longer in the morning usually.
